Tenants get locked out at the most inconvenient times. We provide 24/7 emergency lockout service so your tenants aren't left waiting on the street. Fast response means fewer complaints and better tenant satisfaction.
Lock Changes Between Tenancies
Security best practice requires changing locks between tenants. We schedule lock changes to coordinate with your turnover timeline, ensuring new tenants move into a secure property with fresh keys.

Many insurance policies now require anti-snap cylinders and other security measures. We upgrade rental properties to meet the standards most insurers ask for (BS3621 / TS007 / SS312 Diamond) and provide certification for your records.
Master Key Systems
For landlords with multiple properties or multi-unit buildings, master key systems allow you access to all properties while tenants only access their own unit.
Lock Repairs and Maintenance
Prevent emergency callouts with proactive lock maintenance. We repair worn mechanisms, adjust misaligned doors, and replace faulty components before they fail completely.
Bulk Pricing for Multiple Properties
Managing several rental properties? We offer competitive pricing for landlords upgrading or maintaining locks across multiple units or properties.

Lock Change Services Between Tenancies
Correct lock changes between tenancies are critical for tenant security and insurance compliance. Our streamlined process ensures every turnover is completed efficiently.
Schedule Coordination
We work with your turnover timeline. Book us when the old tenant moves out, and we'll change locks before the new tenant arrives.

Common Landlord Locksmith Situations
We've seen every type of lock issue that affects rental properties. Here's how we handle the most common situations.
New Tenancy Lock Changes
Best practice and often an insurance requirement is changing locks between tenants. This prevents previous tenants from retaining access and ensures new tenants have secure, fresh keys.
Tenant Lost Keys
When tenants lose keys, you need fast resolution. We can cut new keys, change cylinders, or rekey locks depending on the situation and your preference.
Broken Lock Repairs
Tenants report broken locks, stuck mechanisms, or keys that won't turn. We diagnose and repair lock issues quickly, often completing repairs same-visit with parts we carry in our van.
Tenant Lockouts
Locked-out tenants need immediate help. We respond fast with non-destructive entry methods, getting your tenant back inside without damage to your property.
Security Upgrade Requirements
Insurance companies increasingly require anti-snap cylinders and specific security standards. We upgrade rental properties to meet these requirements and provide the necessary certification.
Vacant Property Security
Between tenancies, vacant properties need securing. We install additional security, check all access points, and ensure your empty property is protected from unauthorized access.
Master Key Systems for Multiple Properties
A master key system allows you (the landlord) to access all properties or units with a single master key, while each tenant only has a key that opens their specific property or unit.
